The Feeling is Mutual

 

Mutual funds are shared investments. That means they use money from multiple people to invest in a basket of stocks, bonds, or other securities. Although mutual funds provide an easy way for people to diversify their portfolios, these investors won’t actually own shares of any of the companies the fund invests in. Instead, they’ll own shares of the mutual fund itself, which invests in the companies for them. The result is generally a less risky investment overall—but also a potentially lower rate of return.

Investors can purchase shares of a mutual fund through a brokerage firm, but the most common way people invest is through their 401(k) plans. Most mutual funds have a minimum investment (which can range from $500 to thousands of dollars), but some have no minimums.

The four main categories of mutual funds are stock funds, bond funds, money market funds, and target-date funds. The biggest difference among these four types of funds is the types of securities they invest in. Stock funds, for instance, invest in the stock market. Index funds—which track a specific market index (such as the S&P 500 or Dow Jones)—are among the most well-known types of stock funds.

One Story We're Taking Stock In

 

When budget airline Spirit announced its shutdown in May 2026 after its second bankruptcy filing collapsed, it would have made sense to assume its employees would no longer be working. And while that was the case for the majority of Spirit employees, it turns out there's a skeleton crew behind the scenes that is still hard at work closing the curtains on the airline's business at large.

 

The feature story below—one of the most fascinating we read this week—details exactly how a business as large as Spirit is unwound. Spoiler: While Spirit leased many of its aircraft, some of its assets are still being sold off, from its flight simulators to its institutional knowledge.
